About 2000 Series Aluminum Tube Aluminum sheet

The main alloy element of 2000 series aluminum alloys is copper so the alloys are also called Al-Cu alloys. After heat treatment. 2000 series aluminum alloys have similar mechanical properties to low-carbon steel. lt is prone to stress corrosion cracking, so arc welding technology is not suggested.

2014 aluminum alloy can be applied for occasions with requirements of high strength, high hardness and high temperature.It can be used as aircraft materials, forgings thick metal plates and extruded materialswheels and structural parts, spacecraft parts the first fuel tankof multistage rocket truck frame, suspension parts.

2219 aluminum alloy can be applied for oxidizer tank in space racketsupersonic aircraft skin and structural components.The operatingtemperature of 2219 aluminum alloy is about -270~300Cit has good welding performance and high fracture toughness.During T8 statethe aluminum alloy has good resistance to stress corrosion cracking

2618 aluminum alloy can be used for making die forgings and impact forgings,as well as piston and aircraft engine parts.

2A50 aluminum alloy is used for makina complex shaped medium strenath spare parts.High-strength forged aluminum has high plasticity in hot state and is easy to forge and stamp; it can be strengthened by heat treatment, and its strength after quenching and artificial aging is similar to that of hard aluminum; the process performance is better, but it has extrusion effect, so longitudinal and transverse The performance is different; the corrosion resistance is good, but there is a tendency of intergranular corrosion; the machinability is good, the resistance welding, spot welding, seam welding performance is good, and the arc welding and gas welding performance is not good.

2A11 Aluminum is one of the earliest used duralumin, commonly known as standard duralumin. It has medium strength, good plasticity in annealing, hard quenching and hot state, and can be strengthened by heat treatment. It can be used in quenching and natural aging state. It has good spot welding performance. When 2A11 is used as solder for gas welding and argon arc welding, it tends to crack; Aluminum clad sheet has good stability, but the corrosion resistance of non aluminum clad sheet is not high, and there is a tendency of intergranular corrosion when heated above 100 ℃
